We're dividing 83946 by 3 
The aim is to understand the frequency of 3 in 83946.

Moving on to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Going ahead to step 2:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 21 from 23 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 3:
3 goes into 29 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
If we subtract 27 from 29, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 4:
3 goes into 24 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2798.0
Subtract 24 from 24 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

On to step 5:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 27982.0
Subtracting 6 from 6 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 27982.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27982.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 27982.0, with a leftover of 0.0.
